Grid-type thrust reverser for turbojet engine

A cascade thrust reverser for a turbojet engine configured to form at least one portion of a downstream section of a nacelle accommodating the turbojet engine, the cascade thrust reverser comprising:

• a front frame adapted to be mounted downstream of a fan casing and supporting thrust reverser cascades;
• an O-type thrust reverser movable body having a cylindrical shape around a longitudinal central axis and comprising an inner wall adapted to delimit a cold air flow path with an inner structure, the inner structure surrounding the turbojet engine, and an outer cowl, the O-type thrust reverser movable body being slidably mounted along the longitudinal central axis between a direct jet position in which the outer cowl covers the thrust reverser cascades, and a thrust reversal position in which the outer cowl uncovers the thrust reverser cascades;
• and
• a cradle which is configured to link an upper portion of the O-type thrust reverser movable body on a suspension pylon of the nacelle to provide sliding of the O-type thrust reverser movable body,
• wherein the O-type thrust reverser movable body comprises a first half-portion and a second half-portion, each of the first half-portion and the second half-portion being semi-cylindrical and linked to one another in a lower portion of the O-type thrust reverser movable body by a first dismountable link device, each of the first half-portion and the second half-portion of the O-type thrust reverser movable body being pivotally mounted about a longitudinal pivot axis B, between a closed position and a butterfly open position for removing the turbojet engine, via the cradle.
